Application led December 21, 19,09. Serial No. 534,275.

To all whom it my oncem:

- le it known that. l', CHARLES A. SMITH, a citizen of the United States, residing at the oit of Philadelphia, iu the county ot Philade phia and State of Pennsylvania, have invented a new and useful leneil, of which the following is a specification.

My invention relates to a pencil having means for propelling the lead7 marker,y or marking material, and may be oi' the type shown in Letters Patent of the United States No; esaoo, api-.ii ei, i908. t

It isthe objectI of my invention to provide in such peneil ineens for preventing rotation of the lead or other marker with respect to the barrel or body of the pencil as such lead or marker is propelled, and to prevent the. marker receding into the barrel or body ot` the pencil when oree or pressure is exerted upon the lead or marker. To this end .l provide means in fixed relation with the body or barrel of the pencil and engaging a ineinber secured to the lead or niarlier, such meinber engaging with the propelling means, such as a helix, preferably of wire or metal ribbon. 'The means in fixed relation with vthe barrel or body of the pencil may talte thel Iforni of a wire extending throughout the lenoth ot the body or barrel of the pencih within the saine, and secured at its ends to the pencil barrel or body, or to members in fixed relation with the pencil barrel or body. @r such .ineens may take the form of a groove or channel in the bore of the barrel or body and extend through substantially the entire length ot' the bore. 0r the xed means niay talto any other suitable forni.

For an illustration ot' soute ot the forms my invention may take, roter-eure is io-be had to the accompanying drawings5 in 'l' nre l a longitudinal section through e eil involving my invention. Fig. is longitudinal elevational view, on larger seale, ot the paris reiuoved 't'roiu the barrel or body of the pencil.

Referring to the drawings7 l is the hollow barrel or body oi the pencil, t'oriued ol' spirally wound paper, or other suitable inaterial, iii the manner well understood iu this` arti or the body or barrel l may be toi-ined ot' wood or any other suitable iuateriali. iltthe pointed oud L ol1 the pencil there is secured within the'bore ot the barrel or bodv i a i'errulo Il serving as a guide for the lead or marker 4. At the other end ot thedlnrrel or body l there is secured thereon a fer-rule 5 having the inturned edge or lip 6 engaging in the groove 7 ot the finger piece which latter niay rotate or revolve with respect to the ferrule 5 and the body l, but, in such rotation is Confined by the lip (3 and .the groove 7 from longitudinal movement with respect to the pencil body l. At its inner end of diminished diameter the linger member S is secured at 9 to the propelling' helix l0, here shown as a helix of metal ribbon, suoli helix surrounding the marker 4l.- Secured upon the marker -l at its end remote troni the point is ay short `wire helix 1l, preferably ot' the saine pitch` as the helix l0. Upon the short helix 1l is :formed an eye or other projection l2 which extends outwardly between neighboring turns or eonvolutions oi the helix l0. This eye l2 embraces or surrounds the wire 13 disposed outside of the helix 10 within the bore or the body or pencil l and secured at its one end between the ferrule 5 and the bot y l and at its other end between the 'torride 3 and the body "i, l

By turning; the linger member 8 with respeet lo the barrel or body 1a the helix l0 is revolved and because of such revolution the short helix il secured to the marker Ll is advanced longitudinally with respect to the barrel or body l., thus moving the marker 'forward or backward according to the direct-ion of rotation ol' the linger ineinber 8. short, helix 1l is, however, positively provented Ylroin rotating); bythe wire lll; but the helix 'il is nevertheless inornble lungitudinally ot' the body l, the eye or projets 'tion l2 slidino' lenotnwiso n von le wire lil.

lt follows, therefore, that any "force, even such as will break the point ot thev inarlter inay he exerted longitudinally oi the inarler fl at its point`r while in the act, ot writing', or

otluirivise` without forcing suoli inarher baeliwardly into the barrel l out oli operative writing' position as is soule times possible when the short helix il is not positively prevented from rotation with respect to the barrel or body l.

what l ela'nu is;

l. peni-il haviup` a hollow bodyj it helix revoluble` within the saine, a inarlcer, a niein her serured upon said marker?, projection ou Isaid uuuuher, and u wire engaging said The eye or extension i2 upon the rojection extending 'longitudinally of the gore of said body and in fixed relation thereto.

2. A pencil having a hollow body, a helix revoluble Within the same, a marker, a member lsecured upon said marker, an eye on said member, and a Wire extending through said eye and extending longitudinally of the bore of said body.l

3. A pencil vhaving a hollow body, a helix revoluble Within the same, a ferrule on said body for maintaining said helix in position, a marker, a member secured upon said marker, a projection on said member, and a Wire engaging said projection extending' .longitudinally of the bore of said' body and secured by sai'd ferrule.

4. A pencil having a hollow body, a helix revolublewithin the same, a marker Within said helix, a Wire coiled about said marker andv having an eye formed of said wire extending through neighboring convolutions of said helix, and a wire extending through said eye and extending longitudinally of the Abore of said body and infixed f relation thereto. l

In testimonyvwliereof I have hereunto affixed my signature in the twol subscribing Witnesses.
